as will enable others skilled in the art tov which it appertains to makeand use the same.

This invention relates to improvements 1n adjustable book stands andmusic racks.

One object of the invention is to provide an adjustable book stand andmusic rack adapted to be quickly and easily attached to the arm of achair or other support and to be readily adjusted to support a book ormusic sheet in the desired position.

Another object is to provide a stand or rack of this character having animproved construction and .arrangement of clamping devices whereby themembers of the rack may be quickly adjusted to the desired angles andsecurely clamped in position.

With the foregoing and other objects in view, the invention consists ofcertain novel features of construction, combination and arran ement ofparts as will be more fully descri ed and articularly pointed out in theap ended c aims.

In tl ie accompanying drawings: Figure 1 is a front elevation of a standor rack, Fig.

2 is a side view of the same showing the supporting clamp in a differentposition; Fig. 3 is a vertical sectional view of the upper end of thesupporting standard and the adjustable stem or shank of the board ortable of the stand; Fig. 4 is a perspective view of the shank and socketmembers of the adjustable joints of the same;.Fig. 5 is a similar viewof the lower standard engaging member of the shank joint; Fig. 6 is aside view of the lower end of the upper section of the supportingstandard and a vertical section of the socket member of the joint whichconnects the sections of the standard. Fig. 7 is a similar view of theupper end of the lower section of the standard and the head or innermember of the joint clamp.

In the embodiment of the invention I provide a tubular supportingstandard 1 formed in upper and lower sections 2 and 3 com nectedtogether-at their inner ends by a separable cone and socket joint 4whereby the upper section of the standard may be adjusted to any desiredangle and whereby said sections may be separated and the lower sectionalone employed as a support, as will be hereinafter more fullydescribed.

The'joint 4 comprises a socket member 5 having a tapered recess 6 and athreaded socket 7 adapted to receive the threaded lower end of the uppersection 2 of the standard. In the center of the recessed ortion of thesocket member is formed a olt hole 8. The cone member 9 of the joint isprovided with a hollow conically sha ed cad 10 and a threaded socket 11adapted to receive the threaded upper end of the lower section 3 of thestandard.

In the center of the conical head 10 is formed a bolt hole 12 which whenthe members of the joint are engaged coincides with the bolt hole 8 andthrough said alined holes is inserted a clamping screw 13 with whichranged an adjustable table attaching stem or shank 15 on the lower endof which is formed the tapered socket member 16 of a double cone andsocket joint 17 by means of which the stem or shank is adjustablysecured to the upper end of the up er section 2 of the standard. Thejoint 17 is provided on one end with a conically shaped hollow head 18ada ted to frictionally engage the socket 16. he head 18 is providedwith a central laterally projecting stud bolt 19 which is insertedthrough a centrally disposed bolt hole 20 formed in the socket 16. Onthe projectim end of the bolt 19 is screwed a milled dlamping nut 21 bymeans of which the head 18 is drawn into tight frictional engagementwith the socket thereby fastening these parts of the joint together intheir ad usted positions. On the opposite end of the joint is formed atapered socket 22 having a central bolt hole 23. With the socket 22 isengaged the cone sha ed hollow head 24 of this portion of the dou le'oint 17. The head 24 is provided on its iower side .with a hollowthreaded plugor stud 25 adapted to be screwed into the threaded upperend of theupper section oi the standard. liojectlng from the upper sideof the head 2i a stud bolt 20 which is engaged with and projects throughthe bolt hole 22-) in the socket 22 and is adapted to receive a milledclamping nut QT \\-'hereby the head 2% and socket 22 are securedtogether intight frictional engagement after the joint has been adjustedto the desired position.

On the upper end of the stem or shank 15 is formed a right angularlydisposed tapered socket 28 forming part of an adjustable coir nection orjoint between the shank 15 and the spider 29 of the table or board Thesocket 28 is provided with a central bolt hole 31 and is adapted toreceive a conically shaped head 32 forming part of the spider 29. Thehead 32 has formed therethrough a central bolt hole 83 which alines withthe belt hole 31 in the socket and through said allned holes is inserteda clamping bolt 34 on the projecting end of which is screwed a milledclamping nut 85 whereby said head and socket are drawn'together intotight frictional engagement thus securing the spider and table in theiradjusted positions.

The standard isadjustably secured to a chair arm or any other suitablesupport by a clamp 36 having a fixed jaw 37, the engaging surface ofwhich is padded or leather lined. (loading with the fixed jaw is aclamping screw 88 having a padded or leather lined, swiveled headwhereby the clamp is prevented from marring or scratching the object towhich it is attached.

The clamp 36 is provided on its inner edge with a brace plate 39 whichprojects from opposite ends of the clamp for a purpose hereinafterdescribed. On the outer side of the clamp are formed pairs of aperturedclip engaging lugs 40 and ll which are arranged at right angles to eachother. On the .outer side 'or edge of the fixed jaw of the "clamp isformed a pair of apertured clip engaging lugs 42. By means of the lugs40,

41 and 42 the clamp may be secured in different positions to anattaching clip 43 by and with the alined apertures of said pairs.

of lugs is engaged a combined pivot and clamping screw 16 having anoperating wheel 47. The screw 46 has a threaded outer end adapted to bescrewed into engagement with a threaded aperturein one of the lugs ofthe clip and is'provided withan angular stop shoulder tS which engagesthe other lug 15 of the clip whereby when said screw i tightened up thelugs lfrwill be drawn into light engagement with the lugs of the clampengaged therewith thus securing the clamp at the desired angle. \Vhenthe clamp is attached to a chair arm or other support the brace plate23$) will engage the edge of the object and thus prevent the clamp fromturning thereon. I

v The board or table 30 is provided on its lower edge with book or.music supporting plates 4L8) arranged thereon as shown. Adapted to beemployed in connection'with the stand or rack is a book or music holdingclip :30 which is preferably formed of one piece of spring metal andconstructed as shown in Fig. 2 of the drawing.

By constructing the standas herein shown and described it will be seenthat the. same requiring a more extended explanation.

Various changes in the form, proportion and the minor details ofconstruction may be resorted to without departing from the principle orsacrificingany of the advantages ot' the invention as defined in theappended claims.
